#### Web3 Mode

Use for applications that interact with the blockchain.

Best for:

* Wallet integration and management
* Token creation and SPL token support
* Smart contract deployment
* NFT minting and collections
* DeFi interfaces and swap execution
* On-chain data and transaction history

#### Combining Both

The real leverage comes from combining Web2 and Web3 in the same application.

Example: A DeFi dashboard that uses Supabase for user accounts and preferences (Web2) while connecting to Solana for live portfolio data and swap execution (Web3).
